1 how to distinguish pigments from dyes

pigments for rubber

1.1 how is pigment defined internationally

Pigments are generally colored, black, white or fluorescent particles of organic pigments or inorganic solids.

Usually insoluble, it is used when applied to a medium or substance and is essentially unaffected in physics and chemistry.

Organic pigments and inorganic pigments change external colors by selectively absorbing or scattering light.

A pigment combined with a medium and applied to a medium or substance.

You can find a wide range of applications in many manufacturing industries or in inks, paints, plastics or their materials.

Pigments have a crystalline or granular structure throughout the coloring process.

This concept was first proposed by CPMA.

The performance of organic pigments and inorganic pigments in dyes.

Through the strong colored or fluorescent organic substances, change the light to the substrate and transfer color, so that the external color.

Pigments are soluble and insoluble through an application process.

Break any crystal structure now through absorption, solution, mechanical retention, or chemical bonds by ions or covalent bonds.- by ETAD (association of dye and organic pigment manufacturers defined by ecology and toxicology).

It’s all coloring matter or coloring matter.

A simple definition of pigment

Organic pigments are a class of organic compounds that are insoluble in water, insoluble in media, but are highly dispersed particles that stain colored substances.

Dyes are dissolved in water or its liquid other solvents pigments and dyes solubility in water dyes have important applications in various industries.

1.3 the same name for pigments

We commonly have the following pigment: color pigment, colorant, pigment, dye, etc.

  1. How are the pigments classified

azo red

2.1 the chemical structure is divided into these types

According to our pigments can be divided into organic pigments (brown pigment mainly is one of the producers of organic pigment), inorganic pigments.

Other terms are azo pigments (organic pigments) and non-azo pigments.


The organic pigments can be divided into azo pigments and non-azo pigments.

Azo pigment packages include singlet yellow, orange, diazo compound, naphthol, naphthol AS, azo Haidian, benzamidine, azo condensation, metal complex, etc. T

he various CROWNPIGMENT mainly provide red, yellow azo organic pigments.

Non-azo pigments are divided into phthalocyanine (blue), quinacridone, naphthalene embedded benzene, and cycloketone, red light, this indigo, anthraquinone, dioxazine, isoindoline, isoindoles, pyrrole and pyrrole (DPP), triaryl carbon, quinnaphthalene.

Inorganic pigments include titanium dioxide, carbon and plant black, iron oxide, cadmium, lead chromate, chromium oxide green, group blue, iron blue, chromium green, phthalocyanine green, mixed metal oxide, alum, manganese oxide (MNO).

2.2 how are pigments classified by chromatography

Pigment can be generally divided into blue, green, orange, purple, red, yellow, white, black, brown and so on.

Colors are not all independent of each other. Colors are related, and you can vary colors by changing hue and shade. 

2.3 how to apply pigments

Pigments are used in all kinds of industries and people’s life.

For example, in colored objects that people can see, organic or inorganic pigments are used.

In nature, for example, red and yellow are found only in flower or animal skins.

Organic pigments and inorganic pigments have been widely used in industry since the beginning of the chemical industry in the world.

You can use environmentally friendly and inexpensive pigment products all over the world.

The development of the pigment chemical industry makes my earth become colorful.

Organic pigments mainly provide colors for inks, coatings, plastics, and textiles.

You can see colorful pictures in all kinds of bookstores, posters, and advertisements.

Organic pigments are used in large quantities.

The outer walls of our buildings, and the colored floors.

The red and yellow playground track is mainly the application of organic pigments in coatings.

2.4 how to classify pigments by color

The world recognized “color index” color index is a color classification method.

Pigments are divided into yellow pigment, orange pigment (PO), red pigment (PR), purple pigment (PV), green pigment (PG), brown pigment (PBk), black pigment (color), white pigment (code), metal pigment (PM), etc.

Organic pigment is generally divided into pigment yellow, pigment red

  1. How to name pigments

organic pigment

3.1 index number

Organic pigments are internationally agreed upon. For example pigment red 139; Pigment red 179; Pigment yellow 83, etc.

You can find the corresponding product data in the catalogs of various organic pigment manufacturers.

3.2 CAS number

The CAS registration number of CAS RN, also known as CAS number, is the unique digital identification number of a substance (compound, polymer material, biological sequence (biological sequence), mixture or alloy).

  1. How to distinguish between organic pigments and inorganic pigments

Inorganic pigments compared to organic pigments,

The inorganic pigment in industrial production, more control of the cost, so the sale price is lower.

You can complete mass production with simple production equipment and technical support. And the technical requirements for manufacturers have been reduced.

The simplicity of the process and the low cost of equipment compared to organic pigment production results in very high yield.

Very good performance in light resistance.

Compared with organic pigments, they are stable in color even in extremely high temperatures and extremely low base conditions.

So inorganic pigments have been used in building coatings, glass, ceramics, rubber, and plastics.

The advantages of organic pigments

Organic pigments are used all over the world in every field we can imagine.

If you go out in the morning, there’s organic paint in your front door when you open it.

As you walk down the sidewalk, you’ll find prominent warning signs made from organic pigments yellow and red.

Organic paint is also responsible for all the colored cars you can see.

The mass use of organic pigments, whether in industry or military, aviation, or civilian use, has made our world colorful.

Organic pigments are mainly used in ink, coatings, plastics and other fields.

Organic pigments are characterized by a wide range of colors, bright colors, bright colors and so on.

It has high coloring power and many materials can be used.

Pigments have been updated production equipment, COWNPIGMENT machine.

Research and development of different products, such as high-tech pigment yellow, pigment red.

We customize different product features according to customer requirements.

You can provide your coloring power, we provide corresponding samples.

If there are special numerical requirements on high transparency. We also have the corresponding product formula.

For example, in special industries, organic pigments need very high fluidity to be satisfied.

High-performance organic pigments also provide high light resistance.

In high-temperature environments, there are heat resistant pigment products.

According to customer requirements, organic pigment manufacturers will provide high-quality products.

In ink, paint, plastic applications.

Comparison of organic and inorganic pigments in product characteristics.

Chromatographic variety, spectrum narrows more varieties, a more wide spectrum.

Color features low brightness, darkly bright, bright.

Color intensity low color intensity high color intensity.

Special dosage forms less than a variety of commercial formulations.

Heat resistance most high general low performance.

The variety has excellent heat resistance.

Durability (light and weather resistance) most varieties are higher performance varieties with excellent durability.

Acid and alkali resistant some species are best at discoloration decomposition,Excellent solvent resistance medium to fine.

Toxic (heavy metal) some highly toxic varieties (lead, chromium, mercury, etc.) are non-toxic and low toxic.

The above article basically explains the definition and characteristics of inorganic and organic pigments.

In particular, pigments are changing the colors of the world and people’s lives.
